I think part of the problem is the way religion usually turns out in this game. As I mentioned in another thread I've had tons of fun playing priests. Conducting an auto-de-fei in Freke as Turin was more memorable than any battle I ever participated in. The problem is most religions don't get up to such hijinks. Most sit around, tolerate each other and stick to one main realm. It makes for a very boring player experience. If more exciting things happened with respect to religion more people would want to play priests.
I have further notes on that here:
